On the basis of the submitted data a summary has been compiled that can be read on the Bird of the year website:
Many thanks to all who have already submitted their observations!
We would like to point out that all observations made in earlier months are important and please don’t leave them uncommunicated.
We would also like to remind that the observation unit is the group, that is, we ask you to submit observations of different groups separately, not to add up different groups that are active in a larger area.
The Bird of the Year working group wishes all splendid and enjoyable observations!
